Definitions

  • the invention relates to a device for preventing spark flashover between an electrically conductive container and the cooking space wall in a microwave oven.
  • the inventor has set itself the goal of creating a simple and inexpensive device with which the sparkover mentioned above can be prevented.
  • a device leads to the achievement of the object according to the invention.
  • Advantageous embodiments of the invention result from the further claims.
  • the length of the strip-shaped spacers is preferably chosen so that it has a maximum of the length of the diagonal of the container.
  • the required distance between the container and the cooking space wall with two spacers Reached on all sides and the spacers can be packed without changing the outer packaging.
  • a heat-resistant plastic is selected as the material for the spacers, they also serve as handles for removing the hot metal shell from the cooking space.
  • a container A made of an aluminum foil which is painted on the outside and laminated on the inside with plastic consists of a base part 1, a container wall 2 and a sealing edge 3 projecting from the container wall 2 parallel to the base part 1 the drawing, not shown - sealed lid film, which is removed in each case before the introduction of the container A in a microwave oven.
  • 1, 3 strips 4 made of a heat-resistant plastic are arranged on two opposite sides of the container A on the sealing edge.
  • the long side of the strips 4 with a length 1 and a width b protrude the edge of the sealing edge 3 by a measure r, the broad sides by a measure s.
  • the strips 4 ensure that the container A is at a minimum distance r or s from the cooking chamber wall 5 of a microwave oven.
  • the strip 4 is designed as a double strip 4a, b and encloses the sealing edge 3.
  • the strip 4a with an angled strip part 6a partially overlaps the inner part of the container wall 2 and thus prevents the strip 4 from slipping off the sealing edge 3.
  • the strip 4 is designed as a double strip 4c, d.
  • the sealing edge 3 is shaped as a rolled edge 3c and on the other hand the double strip 4c, d is provided with opposing recesses 6c, d which engage behind the rolled edge 3c.
